To all lb/[01ft it may concern Be it known that ii, Fimniinm Gnnan NEAL,esiding at Halifax, in the Province of Nova Scotia, Canada, a citizen ofthe United States of i-Kinerica, have invented certain new and usefulImprovements in lloof Construction; and I do hereby declare that thefollowing is a full, clear, and exact description of the same.

This invention relates more particularly to the cons action of metallicroofs, being intended primarily for application to the roofs oi box-carsand the like although it will be understood that it may be applied withadvantage to the roofs of other structures.

The invention has for an object to pro vide an improved and simplifiedmeans of attaching the metal sheets of theroof to each other and to the"framework of the roof.

For flirt-her comprehension of the invention and of the objects andadvantages thereof reference will be h ad to the following descriptionand append d claims, and to the accompanying drawings forming part ofthis specification in which similar. refereneecharaeters indicate the sime parts and wherein,

Figure l i plan view of a portion of a roof embo n the invention. Fig. 2is a transvcrsa section thereof taken on the line 1. Fig. is an enlargeddetail ion showing particularly one of between the roof sections. Fig. 4is a section on the line 41 Fig. 3, the view being taken lo 'tudinallyof the joint and transversely or the roof. Fig. 5 is a section on theline 5-5 Fig. 4 looking in the same d'rection as Fig. 3.

lily improved rooi comprises a plurality of sheet metal StlillOllS 2which preferably (as shown in Fig. I) extend the full width. of the roofand are laid upon a suitable frame work, the invention being here shownas applied to the roof of a box car'and the framework as comprisinglongitudinal side beams or side plates 3 and transverse supports orcarlincs 4', the side beams consisting of angle bars with their flangesturned outwardly l'rom thoir lop sides While the transverse supports aremade of l -beams with downturned flanges. The side edges of the roofsections or sheets are bent downwardly over the horizontal flanges ofthe side beams as shown at 2 while rivctr 2 secure the sheets to theside beams and carlines. The adjacent edges of these sections aresupported upon the (:H'lllltS and are turned upwardlyand slightlybacluvardly as at 3 and cover or looking strips 4- having downwardly andinwardly projecting flanges 5 are slipped over the flanges 3', theflanges 5 on the strips tcrminatiim at the edges of the root and theflat ends bent around under the outturned flanges of the side beams at10 and rivets 11 passed through these ends 10, the flanges of thesido'bcams, and the main body of the rover strips to hold the latter inposition. The dovetail arrangement; of the upturned and downturnedflanges 3 and 5 (which is clearly shown in Fig. 5 ot' the drawings)serves to look the cover strip in position without any furtherattachments and providcs a rain proof joint between the roof sect-ions.

\Vhat I claim is follows: I

1. In car roof construction, the combination with longitudinal sidebeams and metal roof sections, of a transverse cover strip covering theadjacent transverse edges ol' the root sections and having its endsturned downwardly across the longitudinaledges of said beams and bentinwardly beneath the latter and rivets passing through the beams andthrough the strip above and loclow said beams.

2. in car roof constrm-tion, the combination with longitudinal sidcbeams and metal roof sections having their transverse edges turnedupwardly, of a transverse cover strip overlapping. the edges of'the roofsections and having its (-Hds turned downwardly across the longitudimlledges of said beams and cover strip and bent inwardly beneath said beamsand rivets passing through the beams and through the strip above and below said beams. I

3. In car roof construction, the combinalion with hingitndinal sidebeams and metal roof sections havimg their transverse edges turnedupwardly and their longitudinal edges bent downwardly across thelongitudi beams and cover strip and bent inwardly In testimony whereof,hzuqe signed nix name to this specification, 1n the presence 01' 10 twosubscribing Witnesses.
